Abstract
A test load circuit includes a test load, a current sensor, and comparator. The test load is connected to a voltage source of a power supply. The current sensor is configured to detect the amount of current flowing through the test load. The comparator has a first input connected to a feedback signal having a voltage associated with the test load current, a second input connected to a command signal having has a voltage associated with a target current through the test load, and an output connected to the test load. The output of the comparator has a voltage that is based on the current difference between the target current and the test load current. The test load has a variable resistance that is controllable by the output of the comparator to adjust the test load current and cause the test load current to match the target current.
